Mirsch OM 3-29 "Panorama" effect

Inläggav Lark » 2025-03-27 14:21

Hej and please excuse my lack of Swedish.
I recently obtained a pair of the Mirsch OM 3-29. I moved here recently and been very intrigued by the cool designs of Olle Mirsch. They are in a nice shape and sound well.
However, the cable that is supposed to connect the two speakers together and enable the side tweeters to work is missing.

My problem is double:
1. I do not recognize the type of jack and therefore can't find replacement cable. Any ideas what type is it and where and how can i get one?
2. One speaker has this jack blocked by a broken pin. I need somehow to take it out/ bypass it/ maybe solder it to a new piece of cable?

I hope you can help me solve those issues and get the side tweeters to work. I am hoping it is worth the hassle. They sound nice as is, and the last owner had them for some years without even trying.

I am based in Stockholm and not very DIY savvy unfortunately. I sent emails with photos to shops like HIFI KIT and waiting to hear back. I still unsure how much am i willing to pay to get that fixed tho. Not sure if the Panorama is not just a gimmick.

Any thoughts and ideas would be very appreciated.

Thanks!

Vee-eight has a Mirsch document and that has some info about this one too.

Seems to be a single conductor, so it should be very simple to fix for you.

My guess is a TRS 2,5 mm mono plug.
See picture no 2 at this site:

There is also an (old) link in the thread to Tradera where you can see a picture of the plug and cable.

I have downloaded all the pdf's i could find. But as I don't speak swedish i just put them all in ChatGPT to try and figure out but no luck.

The reddit post is mine.
The cable photo from tradera is the best photo i could find of it but no one yet was able to identify it well.
I can try the 2.5mm TRS

So it is this connector we are talking about? It looks like a 2,5 mm connector to me.

Indeed that's the one.
Ordered a 2.5mm already!

Any idea how can one fix a broken pin inside the jack?
